That's either incompetent reporting or incompetent statistics.  If
one-third believe in A and one-third believe in B, the proportion who
believe in A and B can be anywhere from zero to one-third.

For these particular values of A and B, there is probably a positive
correlation between the two, so the overlap is probably greater than
the one-ninth that would be to be expected if they were independent.
But I'm fairly sure it's not a perfect correlation.
